Disinfect Water with Calcium HypochloriteBoiling your water is the easiest way to make it safe. Bleach (ONLY Calcium Hypochlorite bleach) can also be used to make safe drinking water, but bleach has a shelf life of that is less than 2 years. You can use the active ingredient from bleach and disinfect water with Calcium Hypochlorite. Calcium hypochlorite is granular (or powder) product typically used to chlorinate swimming pools. It is also known as "Pool Shock". We'll use the dry Calcium hypochlorite to make our own bleach solution, to purify water. Once you add water to the Calcium hypochlorite the clock is ticking on it's effective life-span, just like regular bleach. Store the granules dry for long-term storage.
Making the Chlorine Bleach SolutionFirst we need to make our bleach solution. This bleach solution is NOT drinkable, we are using it to treat the water we do want to drink. DO NOT DRINK THE ORIGINAL Chlorine (BLEACH) SOLUTION! Create the Chlorine (Bleach) Solution (used to treat the drinking water...not for drinking directly)
- To make a stock of chlorine solution (do not drink this!) dissolve 1 heaping teaspoon (about one-quarter of an ounce) of high-test (78%) granular calcium hypochlorite for each two gallons (eight liters) of water.
Disinfecting Water for DRINKING
- To disinfect water add one part of the chlorine solution to 100 parts water to be treated.
- Let the mixture sit for at least one-half hour before drinking.
- To remove any objectionable chlorine odor, aerate the water
- First filter the water as best you can (a t-shirt, bandana, shemagh or other fabric will work)
- Double the amount of bleach you add to the water.
- Stir it well.
- Let the mixture stand for a half hour before drinking.
